Gerber is as Gerber does
Wesley T. Nelson•August 2, 2017
Yes! After learning that only gerber products work with Gerber toilets, I installed this gasket with high hopes. It works, with a caveat: being a sponge, it leaked at first while expanding. After about 24 hours after first testing it, I checked it again, and no leaks whatsoever! I'll never buy a Gerber toilet again, because of incompatibility issues, but their parts work!
Perfect fit for Flushmate Pressure Assist Toilet
S. Shelby•March 3, 2017
Perfect Fit! Did our research before purchase to get the right gasket for a pressure assist toilet (Flushmate). Only one deviation from the instructions - seat the gasket on the tank, not on the bottom (bowl) for installation (watched a couple YouTube first!). Everything went easy and no leaks or drips!
A must for a pressure assisted toilet
DLC40•February 1, 2017
Tried to use a standard gasket I bought at the big box store and it only lasted a week. It simply-could not handle the pressure assist of my Eljer toilet. This one has been working fantastic. It is a much more dense gasket than the standard one.
Has a "ridge" or "bevel"
Carlibob•January 1, 2017
Worked perfectly. The "ridge" or "bevel" in this gasket was exactly what my toilet needed. This wasn't obvious to me but another reviewer said it had it and I just want to emphasis it.
Gerber tank and bowls are a pain until you figure out you need a specialized gasket like this.
Joel•July 10, 2016
Used this to replace a "universal" tank to bowl gasket from a repair kit that was causing water to drip from the tank bolts. After swapping gaskets all leaks stopped and everything is clean and dry. Gerber tank and bowls are a pain until you figure out you need a specialized gasket like this.
